Hadith 3:593

Narrated 'Abdullah:

I heard a man reciting a verse (of the Holy Qur'an) but I had heard
the Prophet reciting it differently. So, I caught hold of the man by
the hand and took him to Allah's Apostle who said, "Both of you are
right." Shu'ba, the sub-narrator said, "I think he said to them,
"Don't differ, for the nations before you differed and perished
(because of their differences). "
